Through adopting above-mentioned technical scheme, show according to the experiment, along with strengthening the increase of the quantity that flute rule set up per meter in length direction, H shaped steel and concrete combine to be inseparabler more, but the increase of cohesion is not linear, and the cohesion of promoting when strengthening the flute rule less is little, and the cohesion of promoting when strengthening the flute rule more is not big, so can be according to the reasonable reinforcement flute rule that sets up different cycle length of demand.
The utility model discloses a further set up to: one end of the folded reinforcing rib is welded with the reinforcing groove grains on the upper flange, and the other end of the folded reinforcing rib is welded with the reinforcing groove grains on the lower flange.
Through adopting above-mentioned technical scheme, the welding of book shape strengthening rib and reinforcing flute is direct not with the upper and lower edge of a wing welding, is the area in order to guarantee reinforcing flute internal triangle groove, the stability of the degree of depth on the one hand, and on the other hand can disperse pressure, can not directly damage upper and lower edge of a wing under the pressure-bearing state.
The utility model discloses a further set up to: the folded reinforcing ribs are arranged on two sides of the web plate and are arranged periodically, and the folded reinforcing ribs on the left side and the right side of the web plate are arranged in a staggered mode at intervals of half period.
Through adopting above-mentioned technical scheme, crisscross setting mutually can make H shaped steel roll over shape strengthening rib stress point more dispersed when bearing shearing force and torsion, the structure of protection H shaped steel that can be better, the inseparable degree of the combination of concrete and H shaped steel also can be improved to a certain extent moreover.
The utility model discloses a further set up to: one side of the web plate is kept away from on the top flange and the bottom flange is provided with a plurality of raised strips in a staggered manner respectively, the raised strips form square grooves, and the groove areas and the groove depths of the square grooves are consistent with those of the triangular grooves.
By adopting the technical scheme, the binding force of the H-shaped steel and the concrete is further enhanced.
The utility model has the advantages that: the utility model discloses a set up inside and strengthen the flute and set up square groove externally for this H shaped steel combines more inseparabler when together casting with the concrete, sets up simultaneously and rolls over shape strengthening rib promotion H shaped steel shear and antitorque ability, has promoted H shaped steel as building material's application range and life greatly.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a schematic perspective view of the present invention.
In the figure, 1, the upper flange; 2. a web; 21. folding reinforcing ribs; 3. a lower flange; 4. reinforcing the flutes; 41. a short steel strip; 42. a long steel strip; 43. a triangular groove; 5. a convex strip; 51. a square groove.
Detailed Description
The technical solution of the present invention will be clearly and completely described below with reference to the specific embodiments.
In this embodiment, as shown in fig. 1, the novel H-section steel is composed of an upper flange 1, a web 2 and a lower flange 3, the web 2 is disposed between the upper flange 1 and the lower flange 3, and the web 2 is connected to the upper flange 1 and the lower flange 3 respectively by welding. The web 2 is provided with broken line reinforcing ribs for enhancing the resistance effect of the web 2 to shearing force and torsion. Reinforcing grooves 4 are arranged on one sides, close to the web 2, of the upper flange 1 and the lower flange 3, the reinforcing grooves 4 are saw-tooth-shaped components formed by welding a plurality of short steel bars 41 and a long steel bar 42, the tips of the saw teeth abut against the web 2, then a triangular groove 43 is formed by the two short steel bars 41 and the web 2, another triangular groove 43 with the same shape and size is formed by the two short steel bars 41 and the long steel bar 42 in an adjacent mode, the shape and structure of the triangular groove 43 have certain requirements, the small or large volume of the groove is not beneficial to lifting concrete and H-shaped steel, if the small volume is too, the groove can wrap too much aggregate or no aggregate, and the binding force between the concrete accommodated by the groove and the concrete main body is too poor to promote the binding force of the concrete of the H-shaped steel; if the tank volume is too large, the area is wasted, and the excessive concrete content hardly contributes to the binding force, so that the test results show thatThe optimal area of the triangular groove 43 is about 300-350mm2The groove depth is 3-6mm, and the structure of the triangular groove 43 can ensure that the binding force between the H-shaped steel and the concrete is more reasonably distributed, and the service life can be prolonged. The reinforcing grooves 4 are directly formed on the upper flange 1 plate or the lower flange 3 plate by hot rolling, and the cost is not increased too much.
Broken line strengthening rib one end is welded on the enhancement flute 4 on the upper flange 1, and the other end welding is on the enhancement flute 4 on the lower flange 3, and the slope sets up, and the broken line strengthening rib of 2 both sides of web sets up in a staggered way, and half cycle separates each other for the drop point of broken line strengthening rib staggers, makes the atress more even, and the drop point makes the steel material of atress more on flute moreover, can increase of service life.
The convex strips 5 are arranged on one sides of the upper and lower flanges 3 far away from the web 2, the staggered convex strips 5 form square grooves 51 with the same area and the same groove depth as the triangular grooves 43, and the convex strips 5 can be rolled together during hot rolling and forming of the flange plates, so that the binding force of the H-shaped steel and the concrete is further improved.
It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
